Be it known that I, ALB RT M. Gunner, a citizen of the United States,residing at Charlotte, in the county of lizlecklenburg and State orNorth Carolina, have invented certain new'and useful Improvements inAdjustable Plugs or Sets for Centering, Plumbing, or Setting Spindles,or" which the following is aspecification, reference being had totheaccompanying drawings.

This invention relates to means for plumbing, setting or aligningperpendicularly and in the exact center of a spinning i'inga spindlesuch as used in spinning co't ton orwoolen yarn, worsted, silk, flax,mohair, etc., and particularly to what are known as plugs which areadapted to be set over the spindle and which have an enlarge mentthereon fitting more or less exactly the spinning ring on the ring rail.

In the operation of spinning machines, it is necessary at intervals tonote whether the spindles are exactly concentrictothe spinning ring onthe ring rail so that the spindle may be set or adjusted into perfectalignment with the axis of the ring and absolutely concentric thereto.This has ordinarily been accomplished by the use of an ad-, justingmember in the form of a large bobbin which has a diameter about smallerthan the internal diameter of the spinning ring and which is appliedover the spindle to be plumbed while in motion, this adjust ing memberenablingthe workman to determine or note with the eye the exact distanceall around between the circumference of the plug and the inner edge ofthe spinningring. If the spindle is found not to be in the exact centerof the ring the workman plumbs the spindle by means of'its adjustment atthe bottom '01 setsit so that it will run concentric to the spinningring, which spinning ring is stationary, in the ring rail. This may alsobe accomplished by placing pieces of paper on either side of the base ofthe spindle, thus-throwing'the'aXis oi the spindle in the directiondesired;

My invention has for its object the provision of a plumbing or settingdevice operating on this same principle and embodying a hollow bodyhaving the form of an ordinary spindle bobbin, a collar or core tittedpermanently upon the hollowbody, and a series of bushings of differentdiameters, all of the bushings being adapted to fit upon and haverotative. engagement with larger forms of bushings; v w

said core or collar," each hushing being readily detachable from'thecore or collar to permit another bushing to be putin place tor thetestingof anotherspindle operating with a dit'ferentf sized ring, thesetesting or truing devices doing away with the neces- I sity of using anon-adjustable wooden plug or large bobbin andsaving the time, labor andexpense of having tomakefan entirely new wooden plugfevery time theworkman has spindles to plumb; tor a different sized ring.,diii'erentsized rings" used in any mill, and my invention contemplatesthe use of a set of metal bushings {toruse with each core, thesebushings being ofa size tofit all the difiierent sized rings, usedin'the millfso that whenever it is desired totruea spindle it isfonlynecessary to place upon thecollar the bush- .ing having the properdiameter andthen dispose the bobbin upon the appropriate spindle. i i a-A-furthe r object of the ,lIlVEntlOIliS to so formthese bushings as tomake the bush-' ing relatively light to thereby causethem to be carriedby, the spindle andfbobbin ()rdinarily there are upward of fifty 7 moreeasily and withlessvibration, which is particularly necessary asspindles; are

M; a a A still further object is to provide a collar or coreso constructed that it may be readily set upon the centering bobbineither at the top, bottom or iniddle portion of the bobbin, thuspermitting thebushing to be disposed upon the bobbin either at thebottom, top ortwo-thirds up the ring rail t'i'aversefl i .Other objectswill appear in the course of the following description.

Myinvention is illustrated in the panying drawings, wherein 1 Figure lis a side elevation ofa spindle having myhimp'roved centering deviceappliedthereto, the ring rail and ring being shown in section;

accombushing;

through a collar and bushing having a slightly modified form;

' Referring to these drawings, designates a spindle bobbin that suitablyfits the spindle to be plumbed. This spindle bobbin, which is of usualform or may be specially made, is tubular so as to fit upon the ordinaryspindle and is formed with an enlarged base 11. Mounted upon this bobbinbody 10 at any desired point along its length is a core or collar 12 ofmetal which snugly fits and may be driven upon the plug 1.0 toanydesired point. This core 12 has the lower half of its peripherycentrally beveled, 'as at 13. Above this beveled portionthe diameterofthe core is reduced and externally screw-threaded, as at 14. Used inconnection with this core are a set of bushings 15, These bushings areall alike, in that they are internally screwthreaded, as at 16,to engagethe screw-threads 1 1. When these annular bushings are turned home uponthe core, the under face of each bushing adjacent the centralscrew-threaded within a standard spinningrin'g A mounted son a rail B,leaving a space of about 3 2 between the inner edge of the ring and theperiphery of the bushing.

Thecollars 12 and the bushings 15 may be made of any suitable material,such as woodfiber, aluminum, rubber, wood, etc, and the diameters of thebushings may run fromone inch or less in diameter for fine yarns to fiveinches or greater in diameter for coarse yarns. T-t'will; be obvious, ofcourse, that the collar or core 12 may be made of one material and theannular bushing 15 may be made ofanother material, or that both may bemade of the same material.

Itwil'l be seen that the particular feature of my invention lies in theadjustability of this centering device'and the provision of a core orparent plugmade to receive a series of, bushings or plugs as'a guide toplumbing all sizes of spindles or adjusting the same I with aresultfarmorezaccurate than where the oldsiiigle non-adjustable wooden plug wasused. Preferably the top surface of the bushings will be enameled yellowso that they may be readily distinguished from the rings, just as thewooden plug has been heretofore kyellowed with chalk for the samepurpose.

11.- do' n twis tto be limi d to t e recess ing of thebushings, as thesebushings may be made light in any other suitable manner. The annularrecessing of the bushings, however, lightens the plug or bushing andthis causes the spindle and bobbin to run more evenly and with lessvibration: I do not wish to be limited to threading the bushings on thecore, as it is obvious, as illustrated in Figure 5, that these bushingscould closely fit onto the core without the use of threads and in thiscase the cores 12 maybe provided with an outwardly projecting peg 18,the bushings being provided with a seat 19 for this peg so as to preventthem being easily turned upon the core. It is obvious that it is withinthe purview of my invention to use any or all means within the terms ofthe accompanying claims whereby to receive the bushings on thevcore andprevent the bushings from being easily turned thereon; My inventionmakes more perfect work in the plumbing or centering of spindles, is agreat convenience, and secures a considerable saving in time, labor andexpense.

Though I have only shown two sizes of bushings, it is to be particularlyunderstood that a set ofbushings will consist of a plurality of bushingshaving different diame ters and that there may be as many bushings in aset as required for ordinary practice, and some sets may run to fiftybushings and some sets to from five to ten bushings,but each of thesebushings will have a diameter nearly equal to theinterior diameter'of astandard ring.

In the work ofplumbing spindles all the bobbins are removed and a bobbinthat fits way down on the spindle snugly and properly is selected ormade specially for the purpose. Then the'core or collar 12-ofmy plug isproperly fitted thereto so asto se=- cure it firmly in place either atthe top, bottom or two-thirds up the bobbin body, and this same'testingor centering bobbin with my plug attached at any of the above pointsmentioned is used for plumbing allthe spindles on the spinning frame orsuch spindles as the bobbin has been originally made to fit. Spindlesare plumbed first at the lower end, therefore my plug"must be positionedfirmly on the lower end of a spindle bobbin or testing bobbin, whichisthen placed upon the spindle withthering'rail "stationary attheb'ottomof its traverse and the spindle centered with relation to thisring railv Then when the spindle has been plumbed at the bottom the ringrail is'a llowed to run to the top of its traverse and by using anothertesting bobbin or even the same testing bobbin with my plug attachedfirmly thereto at the top, thespindle is-plumbed at the top withrelation to thering rail and so on. This work is, termedplumbingspindles top and bottom, but some mills prefer, 1 and rebateespeciallyhon coarse yarns tofhavej'their spindles only plumbed; or asit isusually termed in this case, set, with the ring rail positionedtwo-thirds up thelength of the traverse, and for this purpose my plugwould be positioned firmly two -tliird'sup on the aforesaid bobbin totherebyplumb the spindle with relation to the ringrail. While I haveheretofore referred to spinning spin dles, it will. be understood thatmy device may be used for plumbing or setting spindles which are used inspooling or twisting yarn, and it is obvious of course that the collarand bushing may be made of any suitable material and constructed in, anydesired manner.
